Singlespeed HG Cassette Cog

The DMR Singlespeed HG Cassette Cog is a simple, reliable way to run a single-speed drivetrain on any rear wheel built around a Shimano HG-splined cassette hub. Built from CrMo steel, it’s designed to handle the higher chain loads and repeated starts typical of single-speed riding—whether that’s a commuter build, a dirt jumper, or a trail bike converted for low-maintenance simplicity.

• Shimano HG-spline fit - Installs on standard Shimano HG-compatible cassette freehubs for straightforward single-speed setups
• CrMo steel construction - Prioritizes durability and wear resistance for longer service life under single-speed torque
• Single-speed specific solution - Keeps the drivetrain clean and simple for riders who want fewer parts to adjust and maintain
